Co-hosted by Creative Commons and the Internet Archive, this celebration will feature a keynote address by Lawrence Lessig, lightning talks, demos, multimedia displays and more to mark the “re-opening” of the public domain in the United States. The event will take place at the Internet Archive in San Francisco.

The public domain is our shared cultural heritage, a near limitless trove of creativity  that’s been reused, remixed, and reimagined over centuries to create new works of art and science. The public domain forms the building blocks of culture because these works are not restricted by copyright law. Generally, works come into the public domain when their copyright term expires. But U.S. copyright law has greatly expanded over time, so that now many works don’t enter the public domain for a hundred years or more. Ever since the 1998 Copyright Term Extension Act, no published works have entered the public domain (well, none due to copyright expiration). But for the first time in 20 years this January, tens of thousands of books, films, visual art, sheet music, and plays published in 1923 will be free of intellectual property restrictions, and anyone can use them for any purpose at all.

Join creative, legal, library, advocacy communities to celebrate the public domain growing again for the first time in decades, and come network with an amazing lineup of people and organizations who will help us welcome this new class of public domain works.  Presenters include Larry Lessig, academic, political activist, and founder of Creative Commons, Corynne McSherry, legal director of the Electronic Frontier Foundation, Cory Doctorow, science fiction author and co-editor of Boing Boing, Pam Samuelson, copyright scholar, Ryan Merkley, CEO of Creative Commons, Jamie Boyle, the man who literally wrote the book on the public domain, and many others.
